This watermelon lime slushie brings all the best flavors of a summer day into one glass. Chilled and frosty with just enough tartness and a hint of honey, it is a crowd-pleaser for all ages and beats any store-bought version. When I first tried this slushie after a backyard barbecue, my friends returned for seconds within minutes.
I was blown away by how velvety the texture turned out the very first time I blended these up with frozen watermelon. Now the kids beg for it every sunny afternoon and I happily oblige since it is so healthy
Ingredients
- Frozen watermelon cubes: Ensure a frosty slushie texture. Choose seedless and deep red ripe melon for best flavor
- Honey: Gives just the right touch of natural sweetness. Opt for local raw honey if available for extra floral notes
- Fresh lime juice: Brings brightness and makes the flavors pop. Use key lime or regular lime but always fresh squeezed
- Cold water: Helps loosen everything up and you can use sparkling water if you want to add bubbles
- Pick the sweetest watermelon you can find at the market and freeze the cubes overnight for ice cold slush
Step-by-Step Instructions
- Prepare the Fruit:
- Cut ripe seedless watermelon into cubes and freeze in a single layer until solid. This is key for a thick slushie consistency
- Combine in Blender:
- Add the frozen watermelon cubes, honey, freshly squeezed lime juice and cold water into your blender. If you want a sparkling finish, use chilled sparkling water here
- Blend Smooth:
- Pulse the ingredients briefly to break up the frozen melon, then blend on high speed for at least sixty seconds or until the texture is completely smooth and thick. Scrape down the sides as needed to get every chunk
- Taste and Adjust:
- Give it a quick taste and add a touch more honey or extra lime juice if needed. Blend again to mix
- Serve and Garnish:
- Pour into glasses right away while still frosty. Garnish with a fresh lime wedge or a slice of watermelon for a festive finish

Watermelon has always been my go to summer fruit I love how the lime juice wakes up its natural sweetness in this recipe My youngest always tries to sneak the garnish lime slice before finishing his glass

Ingredient Substitutions
If you do not have honey feel free to swap in agave syrup or maple syrup Use mint leaves in place of lime juice for a cooling variation You can even toss in a handful of frozen strawberries for a more berry forward flavor
